Buccaneer is great, but it is not "just off the interstate". There are several places in or around Biloxi. Majestic Oaks, Cajun RV Park. Also several of the casinos are now saying over night parking available. Imperial Palace, Boomtown, Hard Rock, Harrahs and Golden Nugget ... all say over night parking allowed in the parking lot. I know Boomtown added an actual RV park with full hookups. They do charge now, but not sure how much.
